So got me a new to me G8 GT. Time to add a few mods.
Quick background on me: GM master tech so able to access many vehicles and access to unlimited "stock" calibration but very limited knowledge of aftermarket tuners.
My biggest disappointment is that the G8 has torque vectoring - so there goes part of the only fun of a large disp. motor. NEED TO DISABLE!
That is my first step-- to disable torque vectoring - but a mpvi2 plus credits just for that? Yikes, should I wait?
Planning to install my (already owned) "lsa" oem stock boost supercharger. a cam , valvesprings, chain etc, torque converter (zl1) and guess a CAI (maybe) and here is my first question.:
I need to delete DOD (AFM). So need a new cam- should I ls9? or other better for low end torque stage 2? . not racing or drag....its a daily driver...but like a bit of a big cam idle. Not out to get any power trophies. likely wont see a dragstrip (and would like to keep 6l80 tranny in one piece).
Do I need a zl1 fuel pump and larger injectors as I sure I'll be under 550 HP.
And now the main question: If I buy the mpvi2 and credits- can my tunershop which runs hptuners (from what I deduct from their laptops) use my credit to flash? is it locked to my mpvi with the actual VIN? or just ECM VIN?
I have a second ECM that I programmed cars stock calibration with VIN in - does the credit care which ecm gets modified- (so I can have one a little more "aggressive" track tune). or do I need another 2 credits? Is the trans tuning included in the 2 credits?
Since this (supercharger on g8 l76- is a common swap- does HP repository have any existing tunes that I can flash (or copy, paste into my editor) so I can drive car to tuner without damaging engine- (its highway 50+ miles).
Any help advise appreciated.
